Preoperative diagnosis of renal angiomyolipoma was reviewed with emphasis on ultrasound and CT findings. Two cases were reported. Combined use of ultrasound and CT or conventional radiographs (with demonstration of fat radiolucency) are accurate preoperative diagnostic methods. Nephrectomy or unnecessary operation can be prevented. A small asymptomatic renal mass may be incidentally detected during ultrasound examination of the liver and gall-bladder. If CT or conventional radiographs confirm the presence of fatty tissue in the tumor, diagnosis of renal angiomyolipoma can be made. Then ultrasound follow-up is justified.
回顾性分析肾血管平滑肌脂肪瘤的术前诊断，重点关注超声和CT表现。报告了2例病例。联合使用超声、CT或传统X线片（显示脂肪透光性）是准确的术前诊断方法。可避免肾切除术或不必要的手术。在肝脏和胆囊超声检查时可能偶然发现小的无症状肾肿块。如果CT或传统X线片证实肿瘤内存在脂肪组织，则可诊断为肾血管平滑肌脂肪瘤。然后进行超声随访是合理的。
